Class TupleRemovedEvent

java.lang.Object

java.util.EventObject

com.streambase.liveview.client.AbstractQueryEvent

com.streambase.liveview.client.AbstractTupleEvent

com.streambase.liveview.client.TupleRemovedEvent

All Implemented Interfaces:

Serializable

public final class TupleRemovedEvent
extends AbstractTupleEvent

The event dispatched when an existing Tuple is removed. The inherited method AbstractTupleEvent.getTuple() will return null unless the event was propagated from a LiveResult. The LiveResult will propagate the removed tuple since it maintains a local copy of all tuples in the query result.
